Clinical commentary

Apgar scores are clinical indicators of a baby’s condition shortly after birth. The score is based on 5 characteristics of the baby: skin colour, pulse, breathing, muscle tone and reflex irritability. Each characteristic is given between 0 and 2 points, with a total score between 0 and 10 points (AIHW 2018).

An Apgar score of 7 or more at 5 minutes after birth indicates the baby is adapting well to the environment, while a score of less than 7 indicates complications for the baby (AIHW 2018).

Apgar scores at 5 minutes of less than 7 are not specific to any condition and may reflect congenital anomaly, prematurity, perinatal infection, effects of drugs given to the mother for pain relief or anaesthesia, ineffective resuscitation or prolonged hypoxia before birth (Li et al. 2013).  Maternal factors such as increasing maternal age, obesity, maternal morbidity, especially diabetes, and maternal smoking during pregnancy, may contribute to a baby being born with a low Apgar score (Kharkiva et al. 2017; Straube et al. 2010; Zhu et al. 2015).
